1. 首先删除redhat原有的yum
-
rpm -aq | grep yum | xargs rpm -e --nodeps
-
rpm -aq | grep python-iniparse | xargs rpm -e --nodeps
查看是否已经卸载完成:
-
rpm -aq | grep yum
-
rpm -aq | grep python-iniparse
2. 下载yum安装包
-
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-154.el7.centos.noarch.rpm
-
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
-
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
-
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
- wget http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
先安装python,在安装yum-metadata 最后两个yum一起安装。
3. 安装下载的rpm包
rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-3.4.3-154.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
4. 创建文件/etc/yum.repos.d/CentOS-Base.repo
可以使用网易云或阿里云镜像站点:
网易云镜像:
[base] name=CentOS-$releasever - Base baseurl=http://mirrors.163.com/centos/7.4.1708/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/7.4.1708/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/7.4.1708/extras//$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/7.4.1708/centosplus//$basearch/ gpgcheck=1 enabled=0
阿里云镜像:
[base] name=CentOS-$releasever - Base baseurl=https://mirrors.aliyun.com/centos/7.4.1708/os/$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=https://mirrors.aliyun.com/centos/7.4.1708/updates/$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 [extras] name=CentOS-$releasever - Extras baseurl=https://mirrors.aliyun.com/centos/7.4.1708/extras//$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/7.4.1708/os/x86_64/RPM-GPG-KEY-CentOS-7 [centosplus] name=CentOS-$releasever - Plus baseurl=https://mirrors.aliyun.com/centos/7.4.1708/centosplus//$basearch/ gpgcheck=1 enabled=0
5. yum clean all
6. yum makecache(生成本地缓存)
附:yum源变更说明
经查从2018年05月24日起阿里云和网易云镜像站点中对于CentOS 7.4.1708版本的yum源已经不做支持,在镜像站点中附带了一个readme文件说明如下:
解决该站点镜像无法使用的方式有如下两种:
方式一:将上述第4点中所有的7.4.1708替换为7
方式二:将上述第4点中所有的mirrors.163.com或mirrors.aliyun.com替换为vault.centos.org
yum update出现:
